I live on the Fylde, and now that Audio-T have closed we are certainly challenged locally for good dealers. Although, out of the ashes, a new Naim dealer called Vinyl Groove Audio have just opened up in-between Freckleton and Preston. I’ve not visited them as yet, but the owner used to run The Vinyl Groove Cafe in Lytham St Annes (great food!). DNA Audio are only an hour away in Otley, and they have a decent range of Naim & Co kit and are good guys. There’s also Doug Brady in Warrington, Acoustica and Adventures in Hi-Fi in Chester, which all have a good reputation, so there are places roughly an hour away if you weren’t aware of them.
I’ve heard the Focal speakers you own and like them. I think this range were developed after focal acquired Naim and seem a more sympathetic match to Naim amps. Every time I’ve heard the 106 with something like an Atom or a Nova, they have sounded very good. Focal are a bit ‘marmite’ here. I’ve heard Naim & Focal sounding sublime (Kanta & Aria) and also terrible (Utopia) - akin to shaking a bucket of broken glass in time with a one note bass drum. As with all systems, it could have been so many contributory factors - room acoustics, set up, system mis-match etc, so would never sweepingly condemn them.
Your speakers are an easy load for the amplifier, so unless you want to change the sound ‘flavour’, then I’d start by looking at the front end and consider what you want to achieve. As Ian suggested, perhaps the UnitiStar for an improved streaming option for future proofing, and to work alongside its CD player? Alternatively, a better Naim CD player on the used market? Forum bods with greater experience of Naim CDPs will I’m sure chip in their thoughts on that option. Is it worth considering ripping your CDs to a computer or a NAS to act as a server, and then buy one of the new Naim streamers to stream these files, and also future proof as well? Lots to consider, and as ever, a good dealer will help focus the mind as to the choices available.
Good luck and look forward to reading about what you decide to do!
